Hello!

Sorry for the idiot-questions, but someone here has to play the role....

The network geeks “upstairs” are going to make us one big happy Active Driectory family. I don’t have a problem with this as long as it works and last time it didn’t in spades. We think it was because alot of our AD profiles were corrupt, inasmuch as the Exchange migration still doesn’t work properly – all those with older profiles need to have their profiles deleted and newly generated before either AppleMail or Entourage will work with the new shiny Exchange Server.

Anyway, I do have a question regarding reachabbility of the AD Server. The idea is that each of our 20 or so colleges should have it’s own OD Master talking nice to the AD Server and passing on it’s goodies to the OD Replicas. (We have our own OD Master and Replica here already that has been humming along without a hiccup for the last 15 months or so, so the concept is not so new to us). Now I know, that in a pure OD setup, if the Master goes down, the users can still get onto the Replica just fine. If their mobile profiles or network profiles are on that Replica or another Replica all is still well. It could very well be, that the geeks-in-power will require that all stationary machine use network profiles. What will happen in this new AD-world, if the AD Server goes down or the connection to it goes down? Will our network or users be lost, be sitting in front of black-boxes? Or is the AD LDAP info stored on the OD Master (here) as if it itself were head honcho and not some AD Lackey-Server?

greetings

In theory the AD group is going to build in master and replica scenarios into the AD. That said the local machine is supposed to cache the last user login to a machine. I have all of my machines setup to the AD and setup as mobile accounts. When our connection to outside our building went down, people were still able to login, however the logins were EXTREMELY slow.
